C.1.6 How the modules file “program options” programs are run
For checkout, rtag, and export, the program is server-based, and as such the
following applies:-
If using remote access methods (pserver, ext, etc.),
CVS will execute this program on the server from a temporary
directory. The path is searched for this program.
If using “local access” (on a local or remote NFS file system, i.e.
repository set just to a path),
the program will be executed from the newly checked-out tree, if
found there, or alternatively searched for in the path if not.
The programs are all run after the operation has effectively
completed.
